Astronomen entdecken die mächtigsten kosmischen Explosionen seit dem Urknall

Hinkle discovered the existence of these ENTs while combing through data gathered on long-lasting flares originating from galactic centers. Two flares caught Hinkle’s eye, recorded by the European Space Agency’s Gaia spacecraft in 2016 and 2018, respectively.

A third event discovered in 2020 by the Zwicky Transient Facility (ZTF) appeared similar to the two phenomena discovered by Gaia, which gave researchers clues that these belonged to a new class of extreme cosmic explosions. That’s because these events appeared to release far more energy than other known star explosions, or supernovas, and seemed to last much longer.
